<p>For a wide variety of applications, in particular in the building sector, there is a demand for decorative surfaces which have a colouring which can be individually adjusted and is independent of weathering or treatment with chemical solutions. The method of producing a structured surface according to the invention, preferably on rolled copper strips, provides first of all a mechanical treatment, by which the surface is selectively roughened. In a further method step, the roughened surface then receives a coating, applied by thermal spraying with metal-powder particles. Powder particles of aluminium, copper, nickel and tin as well as powder particles of alloys of these materials, for example of a copper-tin alloy, are suitable as the spray-powder material.</p> |
